Carbon has by definition 6 protons. However, its many isotopes can have anywhere from 2 neutrons to 16 neutrons, with 6 neutrons being the most common (~95% of all carbon). Carbon has by definition <b>6 protons</b>.
Any isotope of iron has 26 protons, and a neutral atom has 26 electrons. If the charge is +3 then it has lost three electrons and has 23. But there is no way to know how many neutrons. The number of neutrons could be 30, 31 or 32 depending on the isotope.
